Budget translation (German to english)

Looking for budget translation, for our daily customer support on German-speaking customer. For some German emails which Google translator couldn't translate properly, we will need someone to help us to express it in plain english - no need to do grammar check or even to use proper english - as it is only for our internal reference before we get back to customer. It is suitable for someone who is checking emails at least 3 times a day (morning, noon and evening). Please bid base on the translation volume of 2000 german words. Thanks!
